Code not running cant quit program

Not sure why this wont work. It asks me for the name but after i enter it doesnt do anything else even if i press n. Does not ask for the phone number at all

def ask(question, kind="string")
  print question + " "
  answer = gets.chomp
  answer = answer.to_i if kind == "number"
  return answer
end

def add_contact
  contact = {"name" =>"","phone_numbers" => []}
  contact["name"] = ask("What is the person's name?")
  answer = ""
  while answer != "n"
    answer = "Do you want to add a phone number? (y/n) "
    if answer == "y"
      phone = ask("Enter a phone number:")
      contact["phone_numbers"].push(phone)
    end
  end
  return contact
end

contact_list = []

answer = ""
while answer != "n"
  contact_list.push(add_contact())
  answer = ask("Add another? (y/n)")
end

Your first problem lies in the fact that you forgot the "do" keyword in both while-statements. Secondly, you do not actually print "Do you want to add a phone number? (y/n)" in the add_contact method. When you print this, you also want to allow your program to catch input with "answer = gets.chomp". The following code is a working solution of your example:

def ask(question, kind = 'string')
  print question + ' '
  answer = gets.chomp
  answer = answer.to_i if kind == 'number'
  return answer
end

def add_contact
  contact = {'name' => '', 'phone_numbers' => []}
  contact['name'] = ask("What is the person's name?")
  answer = ''
  while answer != 'n' do
    print 'Do you want to add a phone number? (y/n) '
    answer = gets.chomp
    if answer == 'y'
      phone = ask('Enter a phone number: ')
      contact['phone_numbers'].push(phone)
    end
  end
  return contact
end

contact_list = []
answer = ''
while answer != 'n' do
  contact_list.push(add_contact())
  answer = ask('Add another? (y/n) ')
end
